Kerbal Space Program or KSP for short is a game where you design and fly an rockets, for little green people. They have even released the second version, both equally fun. I have both, and a staggering 526ish hours, make of this what you will.
Most of my launches are a disaster. Only on the 23/07/2020 did I succeed on a even orbit.
This helps me to further explore my love of astronautic design and learn the basics of orbital mechanics, and have great fun. My kerbals (usually) live.
